Pdf Ventilation Requirements For Today S Mechanized

ventilation is a basic component of underground mine. with the development of the mine, electric power cost will be significantly increased in order to offer enough air to working area, which jan 21, 2020 arctic vent control is ventilation on demand system that provides full control over air flow within the mining site. this advanced mine ventilation system has vehicle detection, gas detection, air quality sensors and scheduling possibilities that optimises the airflow underground. the ventilation system works independently and does not require any infrastructure in the form of general mine ventilation. ventilation is particularly important in mines where heavy machinery is in operation, as plant such as drills and long haul dumps have a huge impact on humidity and temperature. On top of this, extraction can release gases which are harmful to staff working below ground.
